This just adds the arch name to the cache branch names, which
means a build on a different arch will not invalidate the other
arch:s build.

This lets you skip rebuilds unless the actual json changes.
This is useful for continuos builds that only run if the json
changes, not on any commit to any git source.
We always put the state in the .flatpak-builder subdirectory of where
you ran flatpak-builder, independent on the location of the json
manifest. This makes sense in general, but is also extra important
when we want to check out the json from git inside the .flatpak-buidler
directory.
This changes what files we look at to only those in this module,
which is generally right, but to handle the base-layer sdk
case we also have to run the python fixup in the initial layer.
Instead of building directly into the app directory we build into a
rofiles-fuse mount of it, which allows us to safely check out the
cache into the app directory using hardlinks (because rofiles-fuse
will not let you modify hardlinked files).
Additionally, every time we commit to the cache we check out all
the new and modified files into the appdir so that we get hardlinks
to the repo for the new files too.
The advantage of having hardlinks to the repo is that we can commit
much more efficient since we don't have to do a full checksum of
the hardlinked files.
There are some issues here:
eu-strip fails due to doing in-place editin
rofiles-fuse is using lots of CPU, unclear if this is faster, needs
measurements
needs testing of how well the fallback works (ie. if fuse is not
working).
rofuse: use kernel caches
rofiles: check out after commit
Use devino cache
Only check out new files from cache after commit
Rebuilding all apps because a minor change in the runtime is way too wasteful
and generated unnecessary app updates, especially since runtimes are supposed
to be API stable.
We add an a --rebuild-on-sdk-change option which you use to disable this feature,
for instance if you're building against an unstable SDK.
This change fixes GCC compiler warnings where a cleanup function was
specified on an uninitialised pointer, which in the view of GCC could
result in an errornous free of uninitialised memory, if the functions
that initialise them do not return NULL.

The --allow-missing-runtimes options will allow flatpak builder to
not abort immediately if the sdk or runtime for the app being built
are missing.
This option will be useless when building anything in the modules
section of the app manifest. The calls to flatpak-build will fail
because of the missing sdk.
However, it may be useful when an application does not require
building anything inside the sandbox, and the application files
will be installed via other means.
This disables build-args support, which is nice when building things
on e.g. a shared build-machine, where we don't want the build to
be able to break out of the sandbox (by specifying e.g. --share=network).
Stop building at a specified module from the json file.
This is useful during development. For instance, you can do --stop-at=main-app
to build all the dependencies into the appdir, then you can do a build of an
already checked out git repo (possibly with changes).
